BOSTON -- Red Sox closer Craig Kimbrel tied a major league record with four strikeouts in one inning here Thursday at Fenway Park.

He joined Tim Wakefield (Aug. 10, 1999) as the only Boston pitchers ever to do it.

The Red Sox won 6-2 over Texas.

Kimbrel struck out Nomar Mazara swinging to begin the ninth inning but Mazara reached on a wild pitch. The ball actually hit Mazara so he should have been out. But home plate umpire Chad Fairchild didn't see it hit Mazara.

Manager John Farrell wanted the play reviewed but there was a replay issue. (MLB is supposed to release a statement explaining the issue).

This was the second time Kimbrel has struck out four batters in one inning. He also did it Sept. 26, 2012 vs. Miami.

Kimbrel hasn't allowed a hit to a right-handed batter all season long. Righties are 0-for-37 against him.

"The guy strikes out the world," said reliever Matt Barnes, who actually looked at Kimbrel's strikeout and walk numbers before the game.

Kimbrel now has 40 strikeouts and just two walks.

"His fastball is seemingly unhittable," Barnes said. "Complement that with the breaking ball he's got which comes right off of that same plain and when he's commanding it like he is, the numbers kind of speak for themselves. It's kind of ridiculous. It's fun to watch."
